In just three years' time, the world will get more power from wind and solar sources than from coal, according to the International Energy Agency.

The IEA predicts in a report that, over the next five years, the world will increase its renewable power capacity by 75% - an amount equivalent to the entire installed power capacity of China today. By 2027, the biggest source of the world's electricity will be solar power, followed by coal, natural gas and wind, the group said.

"Renewables were already expanding quickly, but the global energy crisis has kicked them into an extraordinary new phase of even faster growth," IEA Executive Director Fatih Birol said in a statement.

"The world is set to add as much renewable power in the next five years as it did in the previous 20 years," Birol noted.

Two main factors are driving the rapid shift to renewable energy, found the IEA, which works with countries to develop polices aimed at enabling sustainable energy: price and security.
